SHIPPING CASE.

Application filed March 7, 1922. Serial No. 541,673.

' ping case which will effect a'very large saving in material over thecommon so-called slotted container and has full capacity for itsdimensions as distinguished from the socalled reoessed end container.The so-called slotted container is one made from a single blank in whichthe bottom and top of the case iseach formed by two pairs of relativelylarge overlapping flaps. This container has been very satisfactory inthe past but it requires a far greater.

amount of material than the container about to be described. Where someof the large industries ship thousands of these containers a day a smallsaving in material amounts to thousands of dollars in the course of ayear. Hence it is the aim of all large shippers to adopt for theirshipping departments shipping cases which use a, minimum amount ofmaterial, which afl'ord the maximum strength, and which require aslittle labor cost in their preparation as possible.

Thec0ntainer about to be described fulfills all these aims and has otheradvanta es which will appear when a detailed description has been given.

In a prior patent, No. 1,414,067, April 25, 1922, a case of this generalcharacter is described, but such prior patent claims only the double orbellows-like sealing flap. This double orbellows sealing flapconstruction may or may not be used with the shipping case constructedof the blank here used and put together in the way here described. In aprior patent 1,452,588, April 24, 1923, the method of sealing a shippingcase which is described and shown in this application is described andclaimed. However, this method of sealing can be used on the slottedcontainer or a difl'erent form of container and hence is a separateinvention. In Patent No. 1,430,151, reissued as Patent No. 15,775, thepreferred method of constructing the box described and claimed in thisapplication is set forth and claimed. However, the box here describedand claimed can be constructed by other methods than that claimed insuch patent but not nearly as advantageously. In Patent No. 1,430,150,Sept. 26, 1922, a machine for stitching a container along the lines ofsaid method is described and claimed.

Referring to Fig. 3, it will be seen that three blanks are used, one amain body blank which has the bottom wall a, side walls b and o, and thesealing flaps e and d. This blank is a rectangular blank with scoringsorweakened lines along which it folds. The end blanks are rectangularblanks with shallow c0rner flaps a formed thereon by cutting out thecorners and providing scor' ings. These end blanks are designated f and.g. The corner flaps mare very shallow; in fact, they only have to bethe wdth of material necessary to hold a wire stitch.

Now refrring to Fjig. 9, it will be seen that the main blank can be setover a pair of anvils h and 2'. The end blanks can be lapped over thesides of thejanvilswith one comer flap of each end blank turned Over theside wall c. Simultaneously a lineof stitches can be taken through eachcorner flap in accordance with the method described and claimed inreissue Patent, No. 15,775, and by a machine such as described andclaimed in Patent No. 1,430,150.

over the anvil, as shown may be pulled out Fig. 10, and the same in thedrawings,

operation taken to unite the comer flaps to the bottom wall of the case,and finally, the main blank may be pulled out another step, as shown inF ig. 11, and the corner flaps of the end blanks stitched to the finalside wall b. It will be noticed that the stitches in each. side andbottom wall are not taken in sequence, as for instance, with the finalside wall b. The stitch 13 is first taken at one end and then the stitch14 at the opposite end, whereupon the stitches then follow in sequence.This is not absolutely essential but it is an advantageous operation inconnection with the machine described and claimed in Patent No. 1,-430,150.

When the case has been thus constructed it may be packed and sealed inacc0rdance with the method described. and claimed in Patent No.1,452,588, to-wit, a blade anvil jis first inserted between the largesealing flaps e and d and under the end blank sealing flap lc, as shownin Fig. 6. The stitches 1, 2, 3 and 4 are then taken, leaving anunstitched portion at the middle through which the anvil may be insertedto take stitches 5, 6, 7, 8, 9 and 10 along the line of the meetingedges of the large sealing to the bellows-like flap.

flaps e and d. Then the anvil may be swung around to take the stitches11, 12, 13 and 14 to stitch the two large sealing flaps e and d to theend blank sealing flap m. The anvil may then be withdrawn and the stitch15 taken between the two large sealingflaps e and d as shown in Fig. 7.This leaves a slightly open space where the final stitch is takenbecause the sealing flaps are not united to the underlying end blankflap k. By using the bellows-like flap described and claimed in Patent.No. 1,414,067, this objection is overconie. At the same time, in someplaces the present construction is preferable The great advantage ofthis type of conta mer over a slotte container is that it ehm1nates onepair of deep flaps used on both the top and bottom of the slottedcontainer. These deep flaps are alwaysused on a slotted container forthey are considered necessary for the silicate form "of seal-' mg,.andeven were my wire stitching form of sealing used, it would be noadvantage to lessen their depth because this would only be waste. Theseend flaps all have to be of the same depth in order to cut out a uniform"rectangular blank. Any variation of their depth results in simplywastihg material.

The so-called recessed end case has a blank construction somewhatsimilar to mine but this case does not clinch the stitches on the insideof the container; in fact, the recessed ends are used for the verypurpose of clinching the stitches on the outside of the container topermit sealing of the container.

'With the recessed end box the full capacityof the box in accordaneewith its dimensions 1s not ach1eved. Consequently the box 1s not as-econom1cal as mme e1ther in the amount of material required or in theroom required Furthertwo sets of wide flaps at the bottom of the slottedcontainer, substituting in place a single, solid wall. ,This, of course,effects a very large saving in material, which runs into a great deal inthe course of a year. Furthermore, my container has a reinforcementstitched around all corners of the box,

which makes it very much stronger than either the slotted container orthe recessed end container. It is stronger than the slotted containerbecause the slotted container does not have a double wall at thec0rners. The recessed end case does have a double wall at the cornersbut this\ wall is a projecting and an exposed one and it makes it easyto tear.

By the use of a machine such as shown in my atent No. 1, 430,150, whichsimultaneously stitches both ends of theblank, ractically no more laboror eort is re uired in stitchin the box and setting it up t an is thecase With the slotted container.

It will be obvious that the comer flaps can be stitched to the inside ofthe side walls and bottom walls in place of the outside without alteringthe principle of the invention, so the statements in the claims must bemuch stronger.

. It will also beobvious that the position of the comer flaps as to theblanks and the l0 cation of the narrow and bread sealing fla s in theseveral blanks might be shifted wit out departingfrom my mvention, hencethe claims have been acco1dingly formulated to cover such changes.

What I claim is: V

1. A shipping case of foldable board, com prising three separate blankssomeof Which are provided with integral foldable comer flaps, two of theblanks being end blanks forming each an end of the case, the remain ingblank forming the bottom and two side walls, the end blanks being set insubstanand held there by the comer flaps being folded and secured to theadjoining blank,

the three said blanks being provided at top or charging side of the casewith an aggregate of three or more sealing flaps each integral with ablank, all folded in, and some overlapped and the adjacent flapsstitched to ether without the material of the case being slotted toeffect such stitching.

2. The combination stated in claim 1 in which there are four sealingflaps with two being relatively narrow and stitched to the other twoflapsalong the length of the narrow flaps.

3. The combination stated in claim 1 in which the comer flaps areintegral with the end blanks and stitched to the body blank.

4. The combination stated in claim 1 including four sealing flaps two ofwhich are relatively narrow and integral with the end blanks.

5. A shipping case constructed of fibre board or equivalent material,comprising three separate substantially rectangular blanks cut andcreased to provide two independent end blanks and one independent bodyblank, some of the blanks provided with integral shallow corner flapsthat are foldable to lie against the .adjoining blank with the ends of.the case substantially flush with the ends of the body blank when thelatter is folded up to form the bottom and two side walls of the case,the corners thus formed being substantiall clear and unobstructed insideand out, t e said three separate blanks arranged to present at the topof the case where it is charged a set of three or more sealingflaps'each integral with a blank, all of which fold in and some of Whichoverlap and two of which are relatively narrow, means for fastening thecorner flaps to the blank or blanks againstwhich they lie, and means forfastening the narrow sealing flaps to the remaining sealing flap orflaps, said last mentioned means conslsting of fasteners driven in andclinched, without the material of the case being slotted to efl'ect suchclinching.
